Well it might start now but i don't want to try because i've heard the oil pressure can reach 700psi unregulated and basically destroy every seal and gaket in the engine. Yeah i torqued the cams down right and in the right order too. I checked all that stuff. I really hope it is the oil pump cause i can't think of anything else.

oil pressure is regulated by the bearings all the pump does is supplys volume

There's a check valve in the oil pump that regulates oil pressure.

Other then taking your timing belt off, replacing your cams, and putting the shit together, you didn't do anything else?

PS. If their is somthing wrong with your oil pump, you might as well sell me your used cams cheap so you can fix your problem. Just kidding. I really don't know how to check that shit, never done it. I doubt that would be the problem, unless its just sure fucking coinidence. Cams dont change oil pressure.

Have you tripple checked your CAS, harness's, tention? Could your CAS pooped the bed?

No i didnt change the timing belt i clamped the belt to the cam gears and left them in place as i changed the cams. I think it is a coincidence becasue i have been having weird problems with the dip-stick and i was burn a little oil just before i did the cams. Also I forgot when i got home after the test drive there was a spot of of splattered on the hood and valve cover and i can't figure where it came from. But oh well worst case senerio i do this and it doesn't help and i have a new timing belt and oil pump (well no new oil pump but a different one).

You could have still jumped the timing a tooth or two doing it that way, did you check the timing marks?

Exactly.. Along with a compression test

yah, he is convinced it is the bloody oil pump, hopefully that will fix it, but he is inside watching the fucking simpsons instead of getting his shit on... I wouldn't think that assembly lube would clog the oil pump..... Just a side question, Do you really need to put assembly lube on the cams? Couldn't you just pour oil on them, or put them in a pan full of oil?

Thanks for the input, no i never said the assembly lube would clog the oil pump. I said the oil chek valve which regulates oil pressure has gone bad increasing the oil pressure. Nothing else is wrong i turned the engine over by hand and it was fine until about 3/4 of a turn the it got hard if i left it for a few minutes it was really easy to turn again, when i say it was hard to tunr i mean damn near impossible, i had a 18'' pry bar and could not turn it but after a little while it turn with ease. If anyone can think what else this could be im all ears but i'm sure it's not the timing for two reasons, it ran fine at first and i checked it before i tore it apart and it was fine.

I'm pissed cause i have to take the damn oil pan off to take the oil pump off, i'm pretty close to taing everything off i figure i have 5 hours of work and i'm done. Sorry to rant but i' just a little annoyed.

MexRocket · #40 05-07-2006, 11:00 PM

It shouldn't be that bad, Myabe an hour to take the t-case off and the exhaust, draining the oil would be like 20 min.... oil pan should take like 10-20 min, then cleaning and shit.... fuck... that is like 3-5 hours.... because you got to put that shit together as well, and it is always harder to put shit back together... Maybe being on the hill will give you a little more leverage when putting the t-case back on...

There are a couple of unrelated problems being described here and adding to the confusion, as well as a lot of misinformation/misdiagnosis

I still maintain that it's going to be something simple.

Oil pressure is not regulated, but there is a relief valve immediately after the oil pump. No way it can raise pressure, unless at very high rpm (9-10k) where it can become a restriction raising pressure. The oil pump can not put out any significant pressure turning by hand or even at idle.

Didpstick popping out has nothing to do with oil pressure, and everything to do with crankcase pressure.

Using the "RRE method" to change cams is how I do it too. The cams will still be timed relative to each other, it's the crank you have to worry about. Make sure the marks all still line up. Do a compression test. Then look for the easy/simple problem that is holding you up.

And if I'm up early, it's because I haven't gone to bed yet. 13 hour night shifts are a bitch

Edit> Even with the plugs out it will get harder to turn, but in this case because of the valve spring pressure.

Its kind of amazing what people will believe when Kevin says it but not when I do...anyway ez sorry to say but I think you have a timing problem. Just do a compression test, it will take all of 2 minutes and you can rule something else out.

kjewer1 · #43 05-07-2006, 11:07 PM

I do notice that all the time, but I hope people don't believe things just because I say it.

I'm dfinitely not always right.

ez1286 · #44 05-07-2006, 11:25 PM

I'm still confused as to why it was easier after I waited for a little while, like pressure was built up somewhere and it disipated if i waited a little while. I had the valve cover off and it wasn't always on the same valves. I'm really confused, i have the timing belt off right now but i'm debating continuing with the oil pump change.

blk_srt · #45 05-07-2006, 11:46 PM

has your motor showed any signs of low oil volume? If not there there isn't any reason to change the pump because that is ALL it does. Did all this pressure gradually build up or did it happen all at once? Think about it logically, what causes resistance? There is compression pushing back, but you said you have the plugs out so that is ruled out, there is of course hitting valves, that would cause it to be extremely hard to turn over but it wouldnt just go away, there is...well that is about all I can think of right now. Just get out and do a compression test and figure it out.
